On Wednesday she works for 7 hours, and she receives $20 in tips. How much money does she earn in total from Monday to Wednesday?

Hallie works a total of 7 + 5 + 7 =

<<7+5+7=19>>19 hours For her hourly pay, she earns 19 * $10 = $<<19*10=190>>190 In tips, she receives a total of $18 + $12 + $20 = $<<18+12+20=50>>50 The total amount of money Hallie earns is $190 + $50 = $<<190+50=240>>240 #### 240 A teacher purchased some school supplies that cost $13 and $24. She had the remaining $6 budget from last year and for this year, she was given a $50 budget. How much money remains in her budget after purchasing the school supplies? The teacher's total budget was $6 + $50 = $<<6+50=56>>56. Her total school supplies expenses was $13 + $24 = $<<13+24=37>>37. Hence, the teacher has $56 - $37 = $<<56-37=19>>19 remaining budget. #### 19 Donna cut her pizza into 12 slices and ate half for lunch. She ate 1/3 of the remaining pizza for dinner. How many slices are left for Donna's lunch tomorrow? Her pizza has 12 slices and she ate 1/2 of the pizza for lunch so that leaves 12/2 = <<12/2=6>>6 slices left She eats 1/3 of the pizza for dinner, so she eats 1/3*6 = <<1/3*6=2>>2 slices She had 6 slices and ate 2 slices, so that leaves her with 6-2 = <<6-2=4>>4 slices for tomorrow's lunch #### 4 Lois has 40 books. She gives a fourth of her books to her nephew. From her remaining books, she donates a third of her books to the library. Then she purchases 3 new books from the book store. How many books does Lois have now? Lois gives 40 / 4 = <<40/4=10>>10 books to her nephew Then Lois has 40 - 10 = <<40-10=30>>30 books Lois donates 30 / 3 = <<30/3=10>>10 books to the library Then Lois has 30 - 10 = <<30-10=20>>20 books After purchasing new books, Lois has 20 + 3 = <<20+3=23>>23 books #### 23 Sally is selling boxes of crackers for her scout troop's fund-raiser. If she sells 50% more on Sunday than she sold on Saturday, then she'll have sold a total of 150 boxes on the two days. How many boxes did she sell on Saturday? Let S be the number of boxes sold on Saturday. S+1.5S=150 2.5S=150 S=<<60=60>>60 Sally sold 60 boxes on Saturday. #### 60 A school is planning a community outreach program. Each classroom must raise $200 for this activity. Classroom A has raised $20 from each of two families, $10 from each of eight families, and $5 from each of ten families. How much more money does Classroom A need in order to reach the goal? Classroom A raised 2 x $20 = $<<2*20=40>>40 from two families. They raised 8 x $10 = $<<8*10=80>>80 from eight families. They raised 10 x $5 = $<<10*5=50>>50 from ten families. Altogether, they raised $40 + $80 + $50 = $<<40+80+50=170>>170. Therefore, they need $200 - $170 = $<<200-170=30>>30 more to reach the goal. #### 30 A carnival snack booth made $50 selling popcorn each day. It made three times as much selling cotton candy. For a 5-day activity, the booth has to pay $30 rent and $75 for the cost of the ingredients. How much did the booth earn for 5 days after paying the rent and the cost of ingredients? The booth made $50 x 3 = $<<50*3=150>>150 selling cotton candy each day. In a day, the booth made a total of $150 + $50 = $<<150+50=200>>200. In 5 days, they made a total of $200 x 5 = $<<200*5=1000>>1000. The booth has to pay a total of $30 + $75 = $<<30+75=105>>105. Thus, the booth earned $1000 - $105 = $<<1000-105=895>>895. #### 895 To earn an airplane pilot certificate, Sangita is required to fly 1,500 hours. She has already completed 50 hours of day flying, 9 hours of night flying, and 121 hours flying cross-country. To meet her goal in exactly 6 months, how many hours per month must Sangita fly? Sangita has already flown for a total of 50 hours + 9 hours + 121 hours = <<50+9+121=180>>180 hours The flight time she has remaining is 1500 hours - 180 hours = <<1500-180=1320>>1320 hours Sangita's monthly target must therefore be 1320 hours / 6 months = <<1320/6=220>>220 hours/month #### 220 Ice cream costs $2.00 and toppings cost $0.50 per topping. How much does a sundae with 10 toppings cost? First find the total cost of the toppings: 10 toppings * $0.50/topping = $<<10*0.5=5.00>>5.00 Then add that amount to the cost of the ice cream: $5.00 + $2.00 = $<<5+2=7.00>>7.00 #### 7 Zach rented a car for $150 plus 50 cents for each mile. He drove 620 miles on Monday and another 744 miles on Thursday. How much did he spend? On Monday Zach spent 620*0.5 = <<620*0.5=310>>310 dollars on miles. On Thursday Zach spent 744*0.5 = <<744*0.5=372>>372 dollars on miles. In total, Zach spent 150+310+372 = <<150+310+372=832>>832 dollars. #### 832
